Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a sling for double-box detection. Background Art

[0002] A double container spreader (or double container spreader) is a non-movable telescopic spreader designed for loading and unloading two 20-foot containers at the same time. It is equipped with a specific mechanical structure and control system to achieve simultaneous operation of two containers.

[0003] In the prior art, a double-box detection method and a sling using the method are disclosed in a patent with publication number CN112623936A. The patent can detect the angle change of the container through an angle sensor. If the container tilts when it is lifted, the tilted container will squeeze the detection plate, causing the angle of the angle sensor to change. The angle sensor transmits the angle information to the user, which serves as a warning to the user.

[0004] However, in this patent, the detection plate and the connecting beam are always in a state of rotational connection, and rely on their own gravity to remain vertical. When the sling lifts the double boxes, it will shake. At this time, the detection plate will follow the shaking, causing the angle data of the angle sensor to change frequently, affecting the staff's acquisition and judgment of the angle data. In addition, the sling will vibrate when it comes into contact with the double boxes, and the shaking detection plate will frequently collide with the container or the sling, affecting the service life of the angle sensor. Therefore, a sling with double box detection is needed to meet people's needs. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) According to the utility model, before lifting the double boxes, the cylinders on both sides can be opened to drive the squeezing rods to squeeze the connecting plate, so that the detection plate drives the angle sensor to flip. After the double-box lifting device is locked with the double boxes, the cylinder is controlled to make the squeezing rods move away from squeezing the connecting plate. At this time, under the action of the squeezing spring, the detection plate will be pressed against the side of the container, thereby preventing the detection plate from shaking with the double-box lifting device during lifting, causing the angle data detected by the angle sensor to change frequently, thereby improving the stability and accuracy of the angle sensor. When the double boxes are lifted and tilted, the tilted container will squeeze the detection plate to flip it, causing the angle data of the angle sensor to change, thereby not affecting the angle sensor's acquisition of the angle data.

[0016] (2) When the extrusion rod continuously squeezes the connecting plate, it will drive the first buffer link and the second buffer link to contact one side of the detection plate. When the double-box lifter contacts the double boxes, it will generate vibration and cause the detection plate to shake. The force generated when the detection plate shakes will act on the first buffer link and the second buffer link, compressing the corresponding buffer spring. At the same time, the extrusion spring is squeezed under the action of the extrusion plate, so that the detection plate and the angle sensor are buffered under the action of the extrusion spring and the buffer spring, thereby avoiding direct collision between the detection plate and the double-box lifter during vibration, which may cause damage to the angle sensor.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a double-box detection sling, comprising a double-box sling 1 and an angle sensor 2, wherein a fixing seat 3 is fixedly installed on the double-box sling 1, connecting plates 4 are rotatably installed on both sides of the fixing seat 3, and a close-fitting structure is installed on the two connecting plates 4, and an extrusion rod 5 is slidably installed on one side of the double-box sling 1, and the extrusion rod 5 contacts the two connecting plates 4, and a buffer structure is installed on the extrusion rod 5, and a driving structure is installed on the buffer structure;

[0024] The close-fitting structure includes a detection plate 41, which is fixedly mounted on two connecting plates 4, and an angle sensor 2 is fixedly mounted on one side of the detection plate 41. The same extrusion plate 42 is fixedly mounted on the two connecting plates 4, and an arc rod 43 is movably mounted on the extrusion plate 42. Stoppers 44 and connecting blocks 45 are fixedly mounted on both ends of the arc rod 43, respectively. The stoppers 44 are in contact with one side of the extrusion plate 42, and the connecting block 45 is fixedly mounted on one side of the fixing seat 3. An extrusion spring 46 is slidably sleeved on the arc rod 43, and one end of the extrusion spring 46 is fixedly mounted on one side of the connecting block 45, and the other end of the extrusion spring 46 is fixedly mounted on one side of the extrusion plate 42. When hoisting the double box Before, the cylinders 6 on both sides can be opened, and the output ends of the cylinders 6 will pull the extrusion rods 5 to slide, and the sliding extrusion rods 5 will be squeezed on the two connecting plates 4. The connecting plates 4 will rotate on the fixed seats 3 due to the squeezing, so that the rotating connecting plates 4 drive the detection plates 41 to flip over and compress the extrusion springs 46. After the double-box spreader 1 is engaged with the double boxes, the cylinders 6 on both sides can be controlled to extend their output ends so that the extrusion slopes 510 no longer squeeze the two connecting plates 4. At this time, the compressed extrusion springs 46 will be released and push the extrusion plates 42 and the detection plates 41 to flip and reset. The reset detection plates 41 will be close to the side of the container under the action of the extrusion springs 46 to improve stability.

[0025] In order to prevent the extrusion plate 42 from deflecting, an arc-shaped sliding hole 47 is opened on the extrusion plate 42, and the arc-shaped rod 43 is slidably installed in the arc-shaped sliding hole 47. The flipped extrusion plate 42 will slide on the arc-shaped rod 43 through the arc-shaped sliding hole 47.

[0026] The working principle is as follows: when the double-box lifter 1 lifts the double boxes, the detection plate 41 is used to stick to the side of the container, and the angle sensor 2 is used to detect the changes in the angles of the double boxes and the detection plate 41. If the double boxes are offset during the lifting process, they will squeeze the detection plate 41, causing the angle of the angle sensor 2 to change, resulting in changes in the angle data detected by the angle sensor 2, so as to detect the angle of the double boxes during lifting. Before lifting the double boxes, the cylinders 6 on both sides can be turned on, and the output end of the cylinder 6 will pull the extrusion rod 5 to slide, and the sliding extrusion rod 5 will drive the extrusion slopes 510 at both ends to squeeze on the two connecting plates 4 respectively. The connecting plates 4 will rotate on the fixed seat 3 when squeezed, so that the rotating connecting plate 4 drives the detection plate 41 to flip over. The detection plate 41 will drive the squeezing plate 42 to flip, so that the squeezing plate 42 slides on the arc rod 43, and the squeezing plate 42 that continues to flip will squeeze the squeezing spring 46 to compress the squeezing spring 46, and the squeezing rod 5 will drive the second buffer link 56 and the first buffer link 55 to contact one side of the detection plate 41 during the continuous movement. When the double-box spreader 1 contacts the double boxes, it will vibrate. At this time, the detection plate 41 will shake. The force generated by the shaking of the detection plate 41 will act on the first buffer link 55 and the second buffer link 56, so that the second buffer link 56 flips and drives one end of the first buffer link 55 to move, and the other end of the first buffer link 55 rotates on the two connecting members 54 and pushes the connecting members 54. The buffer slider 53 will slide in the guide slot 57 during the movement of the connecting member 54, thereby preventing the buffer slider 53 from deflecting. The continuously moving buffer slider 53 will slide on the guide slot 57 through the guide slot 59, thereby preventing the buffer slider 53 from slipping out of the guide slot 57. The buffer slider 53 will squeeze the buffer spring 58 and compress it during the movement. On the other hand, the shaking detection plate 41 will squeeze the extrusion spring 46 under the action of the connecting plate 4 and the extrusion plate 42, thereby preventing the detection plate 41 and the angle sensor 2 from directly colliding with the double-box hoist 1 during the vibration process, thereby preventing the angle sensor 2 from being damaged. After the tool 1 is engaged with the double boxes, the cylinders 6 on both sides can be controlled to extend their output ends, driving the extrusion rod 5 to move and reset, so that the extrusion slope 510 no longer squeezes the two connecting plates 4. At this time, the extrusion spring 46 in the compressed state will be released and push the extrusion plate 42 to flip and reset, so that the reset extrusion plate 42 drives the detection plate 41 to flip and reset through the two connecting plates 4. The reset detection plate 41 will be close to the side of the container under the action of the extrusion spring 46, so as to improve stability and avoid frequent shaking of the detection plate 41 due to vibration during lifting, thereby improving the accuracy of obtaining the angle data of the double boxes. If the double boxes are offset, the detection plate 41 will be squeezed to flip it, so that the angle data will change, thereby not affecting the acquisition of the angle data by the angle sensor 2.

The force generated by the shaking of the detection plate 41 will act on the first buffer link 55 and the second buffer link 56, thereby compressing the buffer spring 58. On the other hand, the shaking detection plate 41 will squeeze the extrusion spring 46 under the action of the connecting plate 4 and the extrusion plate 42, so that the detection plate 41 and the angle sensor 2 are buffered by the action of the extrusion spring 46 and the buffer spring 58, thereby avoiding direct collision between the detection plate 41 and the double-box sling 1 during the vibration process and causing damage to the angle sensor 2.
